SCORIE-CALCULA'ILI IN G DEVICE.

Application filed February 24, 1928. Serial No. 620,879.

To, all whom it may concern:

Be it known that I, EDITH VAN AN'rwERP,

' a citizen of the United States, and a resident of Burlingame, in the county ofSan Mateo and State of California, have invented an Improvement in Score-Calculating Devices. of which the following is a specification.

My invention relates to a score calculating device particularly adapted to the game of Mah J ongg and has for its object to simplify and provide a mechanical means for rapidly and accurately calculating scores in said game.

In certain games, for example, the game now commercially known by the trade name Mah Jongg, the values of the hands held by the players at the close of each game are calculated in accordance with assigned values of the various combinations of pieces held by theplayers and in accordance with certain bonus scores for particular combinations. The base score thus obtained is doubled one or more times depending upon the combinations of honor pieces held by the players or in accordance with certain particular combinations of the pieces, such for instance as hands entirely of one suit,

etc. Since the scores frequently attain relatively large amounts, the mental operation of totaling such scores is arduous and mistakes are likely to .occur.

By the use of my invention it is only necessary. to ascertain the relatively low base score and by manual operation only then calculate the total score.

In the drawings accompanying this specification I have shown:

In Figure 1, a perspective view of my improved calculating device,

In Figure 2, a perspective view of the outer izylinder thereof, and

In .ig'ure 3, a' perspective view of the V inner cylinder thereof.

Referring to the drawings, it will be seen that my device comprises two concentrically arranged cylinders, the outer cylinder 1 being slotted as shown at 2, and having arranged longitudinally u on it adjacent to the slot the number 0 doubles. In the example shown the numbers run from 1 to 7, indicating that the scores are to be doubled once, twice, three times, etc.

The inner c linder 3, which. as shown in Fig. 1, exten 5 beyond the outer cylinder has peripherally arranged upon its exposed portlon the possible base scores to which doubles are applicable. These scores begin with the score of 14 and increase by increments of two to 80. Opposite each of the base scores on the concealed portion of the inner cylinder are arranged the doubles appropriate to such score, for, instance, the

score 20 as indicated on the exposed end of the inner cylinder 3 will have longitudinally arranged opposite it on the inner cylinder the double scores 40, 80, 160, 320, 640, etc.

The double scores are longitudinally ex posed on the inner cylinder 3 so as to register with the double numbers 1, 2, 3, etc., on the outer cylinder 1.

In the operation of my device the base score having been ascertained, the inner cylinder 3; is turned until the base score is brought opposite the pointer 4 on the outer cylinder 1. This exposes to view through the slot 2 the doubles appropriate to the base score and after determinating the number of times that the base scoreis to be doubled, the total score may be read under the number on the outer cylinder indicating the number of doubles, Thus, if the base score be 20 and the number of times the base score is to be doubled is three, the inner cylinder 8 is turned until the number 20 on its exposed portion is brought opposite pointer 4, and the double score 160 then appears in the slot immediately under the number 3 on the outer cylinder.

It will be understood that the device illustrated in the drawings and described herein is merely shown by way ofexample of a form of my invention that I consider to be desirable, and I therefore do not intend to confine myself to the precise details shown and described.

What I claim is:

1. A game score calculating device comprising an outer slotted cylinder having the number of doubles longitudinally arranged thereon adjacent the slot, an inner cylinder having the possible base scores preferably arranged thereon and a plurality of circumferential columns of doubles arranged at intervals, each of said columns being arran ed so as to be positioned adjacent the be ore mentioned doubles on the outer cylinder, the numbers of the base scores pro ressively increasin and the numbers in the respective circum erential columns forming permutation series with related columns.

2. A game score calculatingdevice comprising an outer longitudinal y slotted cylinder having the number of doubles longitudinally arranged thereon adjacent the slot, an inner cylinder extending beyond the outer cylinder and having the possible base scores preferably arranged on its exposed surface and a plurality of circumferential columns of doubles arranged at intervals, each of said columns being arranged so as to be positioned adjacent the before mentioned doubles on the outer cylinder, the numbers of the base scores increasing in multiples of a common digit, and the numbers in the respective circumferential columns forming permutation series with related columns.

3. A game score calculating device comprising an outer slotted cylinder having the number of doubles arranged thereon adjacent said slot, an inner cylinder having the possible base scores arranged thereon and a plurality of columns of doubles arranged on said inner cylinder, each of said columns of doubles being so positioned as to be adjacent the before mentioned doubles on the outer cylinder, the numbers of the common digit and the numbeis in the columns of doubles forming permutation series with the numbers of the base scores.

4. A game score calculatin device comprising an outer slotted cylin er having the number of doubles arranged thereon adjacent said slot, an inner cylinder having thepossible base scores arranged thereon and a pluralit of columns of doubles arranged on sai' inner cylinder, each of said columns of doubles being so positioned as to be adjacent the before mentioned doubles on the outer cylinder, the numbers 'ofthe base scores increasing in multiples of a common digit and successive numbers in successive columns of doubles increasing progressively from the numbers in the base scores whereby to form permutation series.

In testimony whereof, I have signed my name to this specification this 15th day of February, 1923.

EDITH VAN ANTWERP.
